I have recently bought one of these Ecocamel shower heads for the Orion that Bailey fit as standard to their posher vans,so someone thinks they are OK

They are supposed to use less water and give a better spray so perhaps we won't have to fill the Aquaroll as often.
The original plan was to get one for the van and one for home as we have an electric shower but I thought I would buy just the one and see what it was like at home first.
I am glad I did as it didn't work particularly well on our home shower so will just use it in the van.
I have kept the old shower head so if we ever change van we can swap them back.
When it has been put to use I will report on its performance.
